    // response body here
    console.log(result.body)
    // get result in json format
    return result.json()
})
.then(json => {
    // here is the json object
    console.log('> json: ', json)
})
.catch(err => {
    console.log('> Error: ', err)
})

Usage

How to use poke

Poke accepts hostname, pokeOptions and the callback function as the inputs. then it returns some methods for you to apply in different scenarios. Omit the callback function if you would like to handle the result with Promise.

promise

const poke = require('js.poke')

// Using promise
poke(hostname , pokeOptions)
.promise()
.then(result => { 
    // do your handling here
    ... 
})
.catch(error => {
    // handle error
    ...
})

callback

const poke = require('js.poke')
// Using callback
poke(hostname , pokeOptions, result => {
    // status code
    console.log(result.statusCode)
    // body
    console.log(result.body)
    // in json format
    result.json(json => {
        console.log(json)
    })
    // error
    console.log(result.error)
})

Form Data

poke(
    'https://httpbin.org/post',
    {
        method : 'POST',
        // Specify your form data with `boby`
        body : JSON.stringify({
            name : 'kfhk!sdkm!'
        })
    }
)
// ...

Listening to events by using `on`

const poke = require('js.poke')
// Using callback
poke(hostname , pokeOptions)
// listen to response retrived
.on('response', result => {
    console.log(result)
})
// on chunk is recieved
.on('data', (chunk) => {
    // handle your data here
    console.log(d)
})
// on request eneded
.on('end', () => {
    console.log('Request is finished')
})
// listening to error
.on('error', (result) => {
    // handle error
    console.log(result.error)
})

Stream

const fs = require('fs')
const poke = require('js.poke')

// get image
poke('https://via.placeholder.com/100x100')
// write data as an image file
.pipe(fs.createWriteStream('image.png'))

Even we can using Poke as a proxy!

const poke = require('js.poke')

const serv = http.createServer((req, res) => {
    if (req.url === '/placeholder') {
        // get image or whatever you want
        poke('https://via.placeholder.com/100x100')
        // pipe response to res
        .pipe(res)
    } else {
        res.end('Bye!')
    }
})
serv.listen(4321)

The Poke Options

The pokeOptions allows you to customize your request.

// The poke option
const options = {
    // POST, PUT, DELETE
    method : "GET", 
    path : "/", 
    port : 3001,
    // will set automatically, you may override the auto-detect value by specify this boolean
    gzip : true, 
    // username and password for Basic Auth
    username : 'foo_user',
    password : 'foo_secret'
    headers : {
        "content-type" : "application/json"
    },
    query : { page : 3 }
    body : JSON.stringify({
        first_name : "Poke",
        last_name : "You"
    })
}

poke('https://foo.api.com', options)

PokeResult

The PokeResult is returned with one of the following types PokeSuccess and PokeError.

PokeSuccess

PokeSuccess contains the req, body, statusCode, json() and headers. call json() returns a promise and parse the body into json object.

PokeError

if the request is failed, PokeError contains error(type: Error) will be returned.

poke('https://foo.api.com', options)
.promise()
.then(result => {
    // status code
    console.log(result.statusCode)
    // body:string
    console.log(result.body)
    // headers
    console.log(result.headers)
    // parse json
    return result.json()
})
.then(json => {
    // handle with parsed json
    console.log(json)
})
.catch(result => {
    // handler error
    console.log(result.error);
})

poke('https://foo.api.com', options)
